Alexandre.J is an eponymous French perfume brand associated with Création Réalisation Marketing Paris, whose corporate record dates to April 2012 and lists “ALEXANDRE J” as its commercial name. Its creative identity joins perfume with object and visual design, drawing on early-20th-century architecture and materials including mother-of-pearl, glass paste, enamel, and pearls. The brand treats perfume as a total work of art, expressed through themed groupings such as The Collector, The Art Deco Collector, and Art Nouveau, with The Elixir Collector presented as a later development. Alexandre.J develops fragrances in collaboration with contemporary perfumers, with Flair Studio and Floralys identified as contributors to its current olfactory universe. Création Réalisation Marketing Paris owns the Alexandre.J trademark and publishes its website. In April 2026, The Collector was relaunched as The Elixir Collector, reinterpreting earlier creations through changes to fragrance direction and bottle design. Black Muscs II is identified as an iconic bestseller and leads that reinterpretation.
